I've never understood why you'd want a bypass switch inside the device you want to bypass, but this one actually makes sense - just flip the switch, pull the whole AC input module out of the broken unit, plug in the replacement and turn it back to UPS. Nice.
It really has to have 20+ kW rating written on it before I expect to find some useful bricks. Up to 20 kW you can still risk that its just TO-247 or Skiip modules :(
nice sir, well u guide me for my mge ups system,its not working on battery power while its charging the batteries,so teach me how i can repair my inverter part,thanx.
Smaller board looks like two phase pfc to me, probably used when charging. Two transformers can acctually be inductors for pfc. Think that you conected it wrong for test. Expect you to demant me in next video. Great job.
I got the board just next to me. Electrolytic capacitors are in parallel and only 450VDC, so if its two phase it would not be 400VAC between phases, but I know where in Denmark it comes from, so it was fed with 3x400VAC+N. The transformers primaries are connected in parallel to a half-bridge of 47N60 IGBTs and the outputs are parallel as well. But enough about that, I will make a video about it :)
@@KaizerPowerElectronicsDk l chose bit wrong wording. Single input phase is converted into DC by two inductors sharing the current. It is called interleaved power factor correction. There are nice application notes with pictures how tranzistors and inductors are arranged. Sometimes are called two phase because tranzistors are switched interchangeably.
What? No pics of the battery? 😔 Looks a lot neater than the 2200VA and smaller units I've torn apart. I'm guessing that it's a double conversion unit, based on the bypass switch.
There was no battery enclosures, but from the manual I see that its the same size of this enclosure, but you can stack 8 or more of those battery packs in a tower!
Often it can cost the same to replace the batteries into an old unit as getting a while new unit with batteries included. Yay consumer society instead of building things to last :(
I can't say it would have been even close cost-wise to replace the entire units that I salvaged. New replacements were $3000 and new batteries were $250 plus a half-hour of work with tools no more sophisticated than a screwdriver. And they had people who could easily do the work.

My team work has finished installing 555 unit UPS EATON 6KVA model 9E6Ki. Thank the God everything is done.
Nice explained.thanks you.
Nice teardown, I was pretty surprised that there are only TO-247 devices and no IGBT bricks.
Definately a lot of useful parts to be salvaged. :)

Nice old inverter. The heatsink with the 4-5 paalel IGBT are in halfbridge connectio. On the ther heatsink...I cannot understand.
Know anything about the eaton 5p UPS and know how to get it back into boot loader mode from a failed firmware? Unit dead wont turn on :( Used to

5:28 I think it mostly for replace faulty unit without cuting the load, pretty smart solution.
I hope it only fails with mains voltage present then :)
Herr Kaiser, how familiar are you with motor drives, VFDs, and designing inverters for appliances?
As familiar as you can see from my projects on www.kaizerpowerelectronics.dk
87kg toroid sounds awesome!
I should have snapped some pictures of it :(
But that was just impossible for me to get out of the container it was in.
@@KaizerPowerElectronicsDk Based on the success of your other hauls, I blame it on 40 days' mains isolation.

Shank's.
May be very good if You SHOW PRINCIPIAL SHEMATIC.
I will remember to include schematics if they are available.
Why does everybody have access to lovely dumpsters
Not dumpsters, metal recycling companies or privately owned metal scrap yards.

I was just kidding you, I know how heavy those things are, and have seen people throw out an entire UPS just because the battery needs replacing.

Hello.have you a diagram this ups ?
No
@@KaizerPowerElectronicsDk plz send your whatsup number
I have eaton 7 rt ups.but that ups is deth.on power on.plz help me repair the ups
So...you found this in a dumster?
Not dumpsters, metal recycling companies or privately owned metal scrap yards.
@@KaizerPowerElectronicsDk ah, nice.
New version 2019 is very downsized
something stick down on your nose.. 😁
